AccountsOS
AI-Native Ledger · Verified · Information integrity: High
Founders pay for bookkeeping they end up doing themselves, then find out where they stand months late. AccountsOS is an AI accountant: Finn does the production work (bookkeeping, reconciliation, VAT and year-end accounts) on a real double-entry ledger, and a person reviews and signs every filing. Founders get their books finished from £10 a month as a sole trader or £20 as a limited company, live the same day, 14-day trial, no card. Accountancy practices run the same product across their whole client book at £12 per live client (Ledger tier £1.50), so their team reviews and signs instead of preparing, 30-day trial, no card. HMRC-recognised for MTD VAT, live in 27 countries.
